近日，从中国海油天津分公司获悉，随着垦利10-2油田Ⅰ期／垦利10-1油田A54井块开发项目10日在天津、青岛的三个建造场地同时开工建造，亿吨级大油田垦利10-2油田正式进入开发建设阶段。

垦利10-2油田位于渤海南部海域，距离天津市约245公里，平均水深约15.7米，是中国海油2021年在莱州湾凹陷浅层发现的大型岩性油气藏，原油探明地质储量超过1亿吨。

该项目包括在垦利10-2油田新建一座中心平台、2座无人井口平台、新铺7条海底管道和4条海底电缆等，是2025年渤海油田上产4000万吨及稠油300万吨产能建设目标实现的关键项目。

该项目CEPC平台组块是迄今为止渤海油田最大组块，组块浮托重量近2万吨，接近浮托船载荷极限。面对组块总重控难题，项目组通过设备重量精准评估、精细化设计等方式为组块“减重”，实现组块与生活楼乃至修井机的整体浮托，为海上联调高效完成打下坚实基础。

Recently, it was learned from the Tianjin Branch of CNOOC that with the construction of Kenli 10-2 oilfield Phase I/Kenli 10-1 oilfield A54 well block development project in Tianjin and Qingdao on the 10th, the construction of Kenli 10-2 oilfield of 100 million tons officially entered the development and construction stage.

Kenli 10-2 oilfield is located in the southern waters of Bohai Sea, about 245 kilometers away from Tianjin, with an average water depth of about 15.7 meters. It is a large lithologic oil and gas reservoir discovered by CNOOC in 2021 in the shallow layer of Laizhou Bay Depression, with proven geological reserves of more than 100 million tons of crude oil.

The project includes the construction of a new central platform, two unmanned wellhead platforms, seven new submarine pipelines and four submarine cables in Kenli 10-2 oilfield, which is a key project to achieve the production capacity of 40 million tons and 3 million tons of heavy oil in Bohai oilfield by 2025.

The CEPC block of the project is the largest block in Bohai oil field so far, and the weight of the block is nearly 20,000 tons, which is close to the load limit of the floating vessel. Faced with the problem of total recontrol of the block, the project team "reduced the weight" of the block through accurate equipment weight assessment and fine design, so as to achieve the overall floating support of the block and the living building and even the workover rig, laying a solid foundation for the efficient completion of the offshore joint deployment.
